DUMPlNG- WAGON.

Specification of Letters Patent,

Patented April 30, 1907.

Application filed October 5, 1906. Serial No. 837,606.

To LLZZ whom it may concern: Be it known that I, WILLIAM T. GABRI- SON,a-citizen 0f-the United States, residing at Columbia, in the county ofLancaster and following is a specification.

This invention relates to dumping wagons, and more especially to thatclass of wagons in whiohhinged bottom gates or leaves are used.

The principal object of the invention is to provide an improved meansfor effecting the closing movement of the gates, so that the edges ofthe same may overlap, .one of the gates closing slightly in advance ofthe other.

A further object of the invention is to so arrange the gate closingmechanism that thegates will be firmly.v and securely held and aperfectly tightjoint formed between them.

A still further object of the invention is to provide an improved formof lever on which the rear end or bight of the gate closing chain may besecured, and which will operate to effect the closing of the gates oneafter the other.

A still further object of the invention is to provide a connecting barof such nature that one of the gates will be moved to closed position inadvance of the other, the order in which the gates close beingdetermined by the resistance .which they offer to the closing movement,so that the left hand gate may close first at one time, while the righthand gate may close first the next time.

A still further object of the invention is to provide an improved chainguiding means which will permit free' movement of the chains withminimum friction.

A still further object of the invention is to- 1 will more fullyhereinafter appear, the inven tion consists in certain novel features ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform,

proportions, size and minor details of. the

structure may be made without departing from the spirit or sacrificingany of the" ad-.

vantages o? the invention.

In the accompanying drawings :Figure 1 is a perspective view of the rearend of the body of a wagon constructed in accordance with the'invention.Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is atransverse sectional view through the body of the wagon, showing thebottom gates in closed position and showing, also, the open position indotted lines. Fig. 4 is an enlarged detail view of a portion of thestructure shown in Fig. 2. Fig. 5 is a sectional elevation of the leveror connecting bar showing the manner in which the chain is attached.Fig. 6 is a detail perspective view of the bar detached. Fig. 7 is aplan view of one of the forward chain guides detached. Fig. 8 is a rearelevation of the same.

Similar numerals of reference are employed to indicate correspondimparts throughout the several figures of the rawings.

The body of'the wagon is-mounted on suitable supporting wheels, the rearwheels beingdisposed at the ends of an axle bed 10, formed of wood, thelower face of the axle having a longitudinally disposed recess in whichis placed a reinforcing bar 11 formed of iron or steel, the bar bein ofless width than the axle for a purpose hereinafter described.

The sides 15, the front 16, and the rear wall 17 of the body may be ofany ordinary construction and formed of any suitable material.

Secured to the outer faces of the side walls 15 are straps 17, the lowerends of which are provided with eyes for the passage of a pair ofpivot-bolts 18tl1at extend for practically the full len th of the gates,and on the gates are secured similar straps 20, also having eyes for thereception of the pivot bolts, the

pivotal connections being preferably so arranged that when the gates arein open position there will be little or no gap between the gates andthe sides 15.

The rear ends of the gates are arranged to fitsnugly against the forwardface. of the axle bed, as will be evident on reference to Fig. 2, thejoint formed being sufliciently close to prevent the passage of finearticles of the load from'the receptacle. ends of the gates are providedwithguard flanges 23 which preferably are formed of angle bar, the upperwebs of these bars bein disposed on lines paral e1 with the front wallof the receptacle, and eing designed'to fit snugly against the outerface of the front T e front.

wall in order'to prevent the escape of particles of the load, and at thesame time to avoid endwise movement of the gates while the wagon ismoving. Secured to, and extend-v ing longitudinally of each of the gatesis a bar 25 that is arranged nearthe front edge of the gate, each barbeing provided at its rear end with a recess in order that it mayproperly with a pivot pin f runs of the chain thence chain bears duringthe wise secured to the fit against the axle, and extending from theends of these barsare chain guiding eyes 26, the inner walls of whichare rounded in order to permit free play of the gate closing chains 27.Near the central portion of each of the bars 25 is a small hanger .orbracket 29 carrying a sheave or roller 30, against which the gateclosing operation, so that force will be exerted at both ends and at thecenter of each gate in order to hold the same tightly closed.

.Secured to the upper central portion of the axle 10 are two straps 30and'31, the base portions of which are secured to the axle by bolts82,'the bolt openings being arranged beyond the edges of the metallicreinforcing bar 1 1 of the axle. The outer strap or bracket 30 isextended up and is bolted or otherrear wall of the receptacle. orbrackets are provided r the reception of a connectinglever 33, thepivotpoint of which is arranged to one side of the center so as to formtwo arms ofunequal length. The up- These two straps per face of thelever is arranged to engage y with the chain 27 the lever being preferabrecessed, so that the links of the seat therein, and securing bolts 36being employed in order to prevent any independent movement'of thechain. The two runs of the ain xt n t gh t id n e -2 and engage with thesheaves or rollers 30, and at the front of the wagon are extended upwardand pass through a guide 38 that is firmly secured to the front wall 16,the two passing to a suitable winding drum 39. The ide 38 is prefer-.ably in the form of a U-S. @Ped bar'of suflicient width to permit thefree passage of the chain, and the inner wall of this bar is rounded, sothat the chain is free to ride thereover, and to accommodate itself tothe Winding operation as the. chain is coiled around the drum. a

That run of the chain which extends from the shorter arm'of theconnecting .lever 35. is a trifle shorter than the other run of thechain, and this insures perfectlapping of the and the formation of atight joint between them to prevent the escape of gates or doors,

the load.

The gate which closes first being the gate which is connected by thechain to.- the shorter arm of the lever, is provided with a pre ewns l pr fl ge 0 formed of'sheet m l, d e t r ate TS-ar anged t -fit ainst is ror fl n e a e the fir sate chain may,

lever 35, but owing to the difference in'the length of the arms, thelonger arm will de scend while the short arm is raised, andthe gate towhich this shorter arm is connectedwill, therefore, be moved to closedposition in advance of the other. After the first; gate reaclies theclosed position with the connecting lever still at an angle to thehorizontal, the continued movement of the chains will draw the seconddoor or gate closed, and as that run of the chain connected totheshorter arm is of less length than the other, the force of both chainswill be employed in closing the second gateand the lever will be pulledfrom its inclined position to an approximately horizontal positionduring the latter portion of the gate closing operation, the forceexerted at this point being sufificientjo filrnly hold the gates closed"anClI make a tight oint between them.

It will be noted that the construction-of the lever is such that therecan be no possibility of said lever sition, or to such I the matter ofclosing of the gate a matterof uncertainty. In all cases the gateconnected. to the shorter arm of the lever must first move to closedposition, and it is not neces sary to employ any auxiliary stops orother moving to inoperative poj pos tlon as would render devices forlimiting movement of'the lever in either direction.
